[OP: ]
There weren't many ways that they could have used to clear all the creatures present in the forest around them and they knew very well the test was designed to make them fight the strong creatures of <AA> rank and above individually.
They only had to fight the creatures that came in their paths. And most of the time, these creatures were a single unit.
There were times when the opponents were a large group but they were creatures that worked together and were of a lower level and class compared to the single opponents that they were facing.
They were strong but not strong enough to deal with the two of them when they were at full power, had their weapons, and in addition to all that, possessed their Storage spaces.
They were forces that one could only fear as there was nothing that they could do against them.
